Distribution grid for high power polyphase supply cable - has connectors of various sizes to take incoming and outgoing cable and individual or grouped subscriber cable and to allow line disconnection

摘要

The grid (1) ensures electrical continuity between the incoming (2) and outgoing (3) cables and the grouped subscriber cable (4) or two cables (5) for an individual subscriber. The three phases and the neutral are joined to connectors (6,7,8) of one or several sizes to grip several ranges of diameter. The radius of curvature is made least for the conductors of largest cross-section. The first connectors which receive the incoming and outgoing cables are placed closest to the axial line (12,13) of the grid. The connectors receiving the other cables are arranged in a fan shape on either side of the line, set back relative to the first connectors. The line is cut-off by disconnecting either the incoming or outgoing cable. USE/ADVANTAGE - False cut-off and stored grid. Allows use with cables of different diameters, and provides easier handling of cable.
